Use curl

CAST Extend has a built in API that can be accessed in a manner of ways. It is therefore possible to download extensions using the API, for example with curl:

curl -# -O -J "https://extend.castsoftware.com/api/package/download/<id>/[<version>]" -H "x-nuget-apikey: <my_api_key>" -H "accept: application/octet-stream"


curl option -#Displays a rudimentary progress bar to show download progress.
curl option -ODownloads the .nupkg file to the current folder using the file name specified on the Extend server. See https://curl.haxx.se/docs/manpage.html#-O
curl option -J

Tells the -O option to use the server-specified Content-Disposition filename instead of extracting a filename from the URL. See https://curl.haxx.se/docs/manpage.html#-J.

<id>

Specify the ID of the extension you would like to download. The ID of an extension always takes the form com.castsoftware.<name>, without any version numbers. You can determine the ID of an extension using the CAST Extend website:

[<version>]
Specify the version number of the extension you would like to download. You can determine the ID of an extension using the CAST Extend website:

This option is not mandatory. When omitted, the most recent version of the extension you require will always be downloaded.


-H "x-nuget-apikey: <my_api_key>"

Sends your your unique API key as a header - this will grant you access without needing to authenticate. You can find your API key in your user profile in the CAST Extend website:

-H "accept: application/octet-stream"Tells the server (CAST Extend) that the client (curl) is able to accept a specific type of binary download.
